Neon Since its introduction to the scientific world, the element Neon has proven to be an important part of science, technology and medicine. As one of the first inert gases to be discovered, it was instrumental in providing valuable information on the make-up of the earth’s atmosphere. Neon has been a valuable asset in modern industry and medicine, as well as a popular method of advertisement. Although it is not as abundant or as popular as some of the other chemical elements, it has played an important role in the progress of some of today’s scientific and medical discoveries. Neon is a colorless, tasteless, and odorless gas. Its symbol is Ne, and its atomic number is 10. Neon’s position on the periodic table is group 8; period 2. The gas’s melting point is -248.59 degrees C and boiling point is -246.08 degrees C. The atomic mass of Neon is 20.179. Neon occurs naturally in our atmosphere, as does nitrogen, oxygen and argon. However, with these three elements making up approximately 99.966 percent of air, neon only accounts for 0.0182 percent. Neon is obtained from the air during fractional distillation (Newton, 355).
